Study Notes
Factors Affecting Drug Addiction
- Urges to use a drug can be increased by various factors, including the rate of onset, duration of action, and rate of clearance from the body.
Relationship Between Clearance Rate and Urgency
- A faster rate of clearance from the body can lead to a stronger urge for another dose, as the individual may experience withdrawal symptoms or a decrease in the drug's effects.
Duration of Action and Addictiveness
- Drugs with a longer duration of action are generally considered less addictive, as they provide a more sustained effect and may reduce the frequency of use.
Features Determining Addictiveness
- According to the introduction to psychopharmacology, the rate of onset, duration of action, and rate of clearance can determine the addictiveness of a drug.
Faster Rate of Onset
- A faster rate of onset is associated with increased addictiveness, as the rapid increase in dopamine levels can lead to greater reinforcement and repeated use.
